In 2022, Alaska began replacing fish-blocking culverts on the Little Tonsina River with a 100-foot bridge. The project received $1.3 million in federal Bipartisan Infrastructure Law funding. The old crossing restricted fish movement and had suffered damage during earlier flooding.

By August 2023, the new bridge was open and the river could flow more naturally beneath it. The project restored access to 70.4 miles of salmon spawning and rearing habitat , benefiting Coho and Chinook salmon. It also improved the road crossing’s resilience to floods and debris.
